2003-09-25  Yoshinori K. Okuji  <okuji@enbug.org>

	incomplete support for VGA console, and this is still very

	* kern/dl.c (pupa_dl_ref): Refer dependending modules
	recursively.
	(pupa_dl_unref): Unrefer depending modules recursively.

2003-01-17  Yoshinori K. Okuji  <okuji@enbug.org>

	Also, add only 1/4 of the upper memory to free memory. The rest
	is used for loading OS images. Maybe this is ad hoc, but this
	makes it much easier to relocate OS images when booting.

	module is too dangerous.

	* include/pupa/loader.h (pupa_os_area_addr): Declared.
	(pupa_os_area_size): Likewise.
	(pupa_loader_set): Remove the first argument. Loader doesn't
	manage modules or initrd any longer.

	* conf/i386-pc.rmk (pkgdata_MODULES): Added linux.mod.
	(linux_mod_SOURCES): New variable.

	* util/i386/pc/pupa-setup.c (setup): Define the internal

	[__linux__] (linux_find_partition): Use a temporary buffer
	REAL_DEV for the working space. Copy it to DEV before returning.
	(open_device) [__linux__]: Call ioctl with BLKFLSBUF to make the
	buffer cache consistent.
	(get_os_disk) [__linux__]: Use the length 5 instead of 4 for
	strncmp. The previous value was merely wrong.
	(pupa_util_biosdisk_get_pupa_dev): Use stat instead of lstat.

	* fs/fat.c (pupa_fat_read_data): Shift 4 instead of 12 when the
	FAT size is 12. The previous value was merely wrong.

	* kern/main.c (pupa_main): Don't split the starting message from
	newlines.

	* kern/term.c (pupa_putchar): Put CR after LF instead of before
	LF, because BIOS goes crazy about character attributes in this
